The colors of my life Are bountiful and bold, The purple glow of indigo, The gleam of green and gold. The splendor of the sunrise, The dazzle of a flame, The glory of a rainbow, I'd put 'em all to shame.

If you mean that the proximity of one color should give beauty to another that terminates near it, observe the rays of the sun in the composition of the rainbow, the colors of which are generated by the falling rain, when each drop in its descent takes every color of the bow.
